Indirect Setting Method By Devices - Mitsubishi Electric MELSEC Q Series Programming Manual

5 SERVO PROGRAMS FOR POSITIONING CONTROL

5.4.2 Indirect setting method by devices

Note) : Device memory data : 1) = 2)
In the indirect setting method
positioning data specified with the servo program.
By using the contents (data) of specified device using the Motion SFC program
(Automatic refresh, etc.), multiple positioning controls can be executed in one servo
program.
The device used in the indirect setting is the device of the Motion CPU but the device
of the PLC CPU.
The device memory composition of the Motion CPU and PLC CPU is shown below.
